1930. Serial No. 433,702.

(GRANTED UNDER THE ACT OF MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 370 O. G. 757) My invention relates broadly to reproducing machines and more particularly to a counter attachment therefor. I

An object of the invention is to provide a counter attachment for a reproducing machine whereby a record of the number'of full or half sheets of paper used by the machine is made.

Another object is to provide a means for disconnecting the counter attachment permitting movement of the paper through the machinewithout a record being made thereof. I With the above and other objects in view the invention consists in the construction, combination and arrangement of parts as will be described more fully hereinafter.

Reference is to be had to the accompanying drawings forming part of this specification in which like reference characters indicate 2 corresponding parts throughout the several views, and in which Figure 1 is a front view of the paper control panel of a reproducing machine with my invention attached;

Figure 2 is a view of the paper control mechanism of a reproducing machine with the outer panel removed;

Figure 3 is a section on the line 3-3 of Figure 2; and

Figure 4 is a detail of a portion of the release mechanism for disconnecting the counter attachment.

Referring more particularly to Figure 1 of the drawings, 5 indicates the handle by which the paper is moved through the machine, 6

the pressure control member pivoted at 7,

whereby pressure is removed from or applied to the rubberized winding rollers turned by handle 5, and which is limited in its pivotal movement by the stops 8 and 9. The number 10 is the paper cutting handle. The amount of paper moved by handle 5 is regulated by an adjustable member 11, that is so arranged that apin 12 will drop into openings 13 when the limit of the desired amount is reached. When this pin drops into the proper opening, it permits stop 14 to move into the path of rotation of handle 5 preventing its further rotation. Handle 5 turns two rollers between which paper 15 (more clearly seen in Figure 2) is fed, the rollers being connected by gears 16 and 17 One of the rollers has mounted on its shaft a gear 18 which engages with a large gear 19, in which the openings 13 are formed.

I have not attempted to give a detailed description of the above referred to parts as they are in general use in substantially all reproducing machines. My invention,which is a counter attachment forand operated by 66' the aforesaid mechanism, will now be described. a As may be seen by referring to Figure 2, large gear 19 is provided with pins 20 that are diametrically arranged near its periphery in such a manner that they will come into contact with a pivoted arm 21 causing it to operate the counter attachment 22 through arms 23 and 24. The ratio between gears 18 and 19 is such that gear 19 will complete 79 one revolution for each full sized sheet of paper passing between the rollers. Therefore, the arm 21 will be caused to move twice-once at the midway point and once at the end of each revolution of the gear, the midway point indicating the end of a half sized sheet of paper. The system of arms 21, 23, and 24 therefore trip the counter dial 25 every half turn of the gear 19. The mechanism for adjusting for the size of 550 sheet of paper, and the means employed whereby the half-sheet counter trips the full sheet counter 26, and the latter the total counter 27 are well known in the art to which they pertain. Neither is it necessary 5 to explain how the counters may be returned to zero reading by knobs 28.

It may be desirable for various reasons to move the paper through the rollers without A a record being kept of the movement of paper. To so move the paper pressure is removed from the rollers by handle 6 which simultaneously disconnects the counter attachment from its operating mechanism. A cam 29 is mounted on shaft 30 to which handle 6 is attached. One end of an arm 31 that is pivoted in a bracket 32 attached to the framework of the machine, engages with the cam, and the other end of the arm is secured to a stud 33 slidably mounted in 1 the framework, and which is attached to the arm 21, as shown in Figure 3. As the cam is rotated arm 31 rides over its surface pulling the stud to the left which in turn moves arm '21 out of the path of pins 20, thereby preventing registration of the counter during the movement of gear 19. Arm 21 is free to be moved in this mannner because of the pivotal connection between arms 23 and 24, arm 21 being connected to arm 23. Spring 34 returns arm 21 to its operative position when handle 6 is turned to again put pressure on the rollers, and a collar 35 on the stud 33 limits the distance which the stud may move toward the front of the machine.

Although I have described my invention in connection with a machine through which paper is fed, it will be apparent that it is not limited thereto, but may be attached to any machine through which a moving strip of material is fed.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment ofmy invention and that minor changes in details of construction, proportion and arrangement of parts may be made with in the scope of theappended claims and without sacrificing any of the advantages of the invention.

and the said actuated arm, and means for operating said member. I

2. An attachment for a reproducing machine including a counter, a train of pivotally connected arms, means operated by the reproducing machine for actuating one of the arms whereby the counter is .actuated through the other of said arms, and means for disabling the train of arms, said means consisting of a shaft, an inclined surfaced collar thereon, a lever engaging with said surface and connected with the actuated arm, whereby the arm is removed from its actuating means when the shaft is rotated.
